c# - ASP.NET AjaxActionLink 请求中存在潜在危险的 Request.Path

Question

我在 MVC ASP.NET 应用程序中有一个 cshtml View 。我只想让用户单击一个按钮并在执行操作之前向用户发出警告。我知道实现我想要的唯一方法是像这样使用 AjaxActionLink

<a role="button" 
   class="btn btn-lg btn-primary" 
   href='@Ajax.ActionLink(
        "Clear Invite Log",
        "ClearInviteLog",
        "Tools",
        null,
        new AjaxOptions { HttpMethod = "GET" },
        new { onclick = "return confirm('Are you sure you want to clear the invite log?');" })'>
    Clear Invite Log
</a>

我的 Controller 的名称是 ToolsController，我要发布到的方法是 ClearInviteLog。问题是，当我单击按钮时，我没有看到警告对话框，而是得到了

Server Error in '/' Application. A potentially dangerous Request.Path value was detected from the client (<).

Stack Trace: [HttpException (0x80004005): A potentially dangerous Request.Path value was detected from the client (<).] System.Web.HttpRequest.ValidateInputIfRequiredByConfig() +9693412 System.Web.PipelineStepManager.ValidateHelper(HttpContext context) +53

我是网络开发的新手，我很困惑。我在这里做错了什么？

感谢您的宝贵时间。

你不需要设置 anchor 标签href值的Ajax.ActionLink，Ajax.ActionLink和Html.ActionLink本身作为 anchor 标签渲染，你只需要直接使用Ajax.ActilnLink:

@Ajax.ActionLink(
    "Clear Invite Log",
    "ClearInviteLog",
    "Tools",
    null,
    new AjaxOptions { HttpMethod = "GET" },
    new 
       { 
         onclick = "return confirm('Are you sure you want to clear the invite log?');",
         @class ="btn btn-lg btn-primary",
         role="button" })
